Legrand Auxiliary Contact 1P Side Mounting for TX3 and DX3 Series

The Legrand auxiliary contact for TX3 and DX3 series is a precision-engineered 1-pole device designed for seamless side mounting on circuit breakers and residual current devices. This component serves as a critical interface for electrical distribution systems, enabling accurate remote monitoring of the switching status of protective devices. By providing real-time feedback on whether a circuit is open or closed, it significantly improves the management and operational transparency of electrical panels in both residential and industrial environments.

Advantages

This auxiliary contact offers high reliability and ease of integration within existing Legrand electrical infrastructure. Its side-mounting design ensures a compact footprint, allowing for efficient use of space within distribution boards without requiring complex modifications. The device is built to maintain consistent performance, ensuring that status signaling remains accurate over long periods of operation, which is essential for maintaining safety standards and proactive maintenance schedules in complex electrical setups.

Suitable for

• Remote monitoring of circuit breaker status
• Integration into industrial automation and control panels
• Residential electrical distribution boards requiring status feedback
• Safety-critical electrical installations

When it may not be suitable

This device is specifically designed for compatibility with the Legrand TX3 and DX3 series. It may not be suitable for use with circuit breakers from other manufacturers or older product lines that do not support this specific side-mounting interface.

Key specifications

• Configuration: 1-pole (1P)
• Mounting type: Side mounting
• Compatibility: Legrand TX3 and DX3 series circuit breakers and residual current devices
• Function: Status signaling and remote monitoring

How to use

Installation should be performed by a qualified electrician in accordance with local safety regulations. Ensure the main power supply is disconnected before attempting to mount the auxiliary contact. The device attaches to the side of the compatible circuit breaker or residual current device using the integrated mechanical coupling. Once physically secured, connect the signal wires to the terminals according to the wiring diagram provided with the main protective device to establish the monitoring circuit.

What to consider before purchase

• Verify that your existing circuit breaker is part of the TX3 or DX3 series
• Ensure there is sufficient physical space on the side of the breaker within the distribution board
• Confirm that your monitoring system is compatible with the signal output of this auxiliary contact

Usage recommendations

Always test the signaling function after installation to ensure the monitoring system correctly reflects the switching position of the circuit breaker. Regular inspection of the electrical connections is recommended to maintain system integrity.
